Crappy support.

Tried to acquire a SynthMaster license second hand. Paid the seller and he contacted KV331 transfer the license. A week went by - with no response from KV331. Had to cancel the deal. The seller did what he could, but KV331 just did not respond. Never getting any of their products.

Sorry that you had this issue. I've had good experiences with KV331 myself. They have a lot of sales, if you sign up for their newsletter or follow them on social media you can save money that way. Buying used software from third party sellers is kind of hit-and-miss IME. I'd be hesitant to formulate your opinions on a company based on your experiences with a third party seller.

I don't think the licenses are transferable. Synthmaster is a really nice synth, never had any problems with mine.

Had several questions through the years and Bulent has always been great. One of my favorite and most used VSTs.

not sure if this is where i report a bug, but in reason 9.5 I'm using synth master one, and when i open the plugin to modify an FM patch I'm making the semitones and octave changes when ever i close and reopen the plugin.

each time i close and re open the semitones are set to 11 and the pitch octaves are at -3.

Been trying for the last three hours to get Synthmaster 2.9 to load without continual prompts to download a license key - which I have done too many times to count. Used every link provided, uninstalled, reinstalled repeatedly. Sent numerous support tickets (knowing I'm outside of business hours). Last support ticket I tried to send landed me on a 404 - File or directory not found. Although it installed into my main VST folder, Reaper will not recognize it. Further, the KVR OSC #73 Users Bank download lands on this: File Not Found: Firefox can't find the file at http://cdn.synthmaster.com/synthmaster/usersdownloads/expansions/kvrosc73usersbank/kvrosc73usersbank.zip?st=oKtKYVAEBY71G4j5vnJ2ig&e=1567993451.

Cleared space in my arrangement specifically to use Synthmaster on a deadline project. Bought into the rave reviews - hook, line and sinker. Demos sure sound great. Yet, here I am sending support tickets to no avail and writing on a forum in desperation. Had the weekend to work on this. What a disappointment.

It behaves as if you had changed the default installation directory to choose another directory... which is write protected.
